Somebody did this with normal 8-bit hardware about 5-10 years ago. Like the current instance, that one also took several hours to get to a commandline prompt.

Somebody did this with normal 8-bit hardware about 5-10 years ago. Like the current instance, that one also took several hours to get to a commandline prompt. It's the age-old trade-off, power versus speed. The more powerful your CPU and peripherals, the less time and/or number of instructions required taken to do each particular job along the way to get to that prompt. I remember looking at the number of instructions required to do 32-bit additions on a 4MHz 8-bit Z80 once. All of those instructions were replaced by one single (and much faster!) instruction on a 33MHz 80386 CPU.
